Chemical Structure

Pcb No. 103 CAS 60145-21-3 chemical structure

Description

Pcb No. 103 (CAS 60145-21-3) is a high-purity analytical reference standard with the molecular formula C12H5Cl5 and a molecular weight of 326.43 g/mol.

Owing to chlorine substitution, an aromatic ring system, Pcb No. 103 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
